That's odd - not sure withholding water would help. Too much nitrogen perhaps? Temp seems less likely since it's been pretty ideal in the 90s for a while now.

Personally I would feed with something high in P. That encourages blooming and root development. I start about 4-7 days after transplanting. I've had lots of bloom and even fair fruit set during this heat. I'm one who don't use a lot of N on tomatoes. My soil is so rich it has basically more than they need to start with. There are many options. You could foliar feed them. This year I have used a liquid bonemeal 0-12-0 and add a little fish/ seaweed that is 0-0-8. This has worked well. Overall my plants have done well. Have had some disease issues. I haven't sprayed anything yet but may start on one area. Jay

Is there a foliar spray with just phosphorous? I know you can buy some sort of Bloom Booster stuff with a 30% rate, but it still has 15% nitrogen, which it seems you already have plenty of....

I am nearing some sort of step in this direction also, Kenny. I've used the withholding water trick at the end of the season to hurry up ripening and suppress continued growth. As we are approaching 1st frost, that works well - as long as we don't get a good rainstorm.

I suppose it might prompt flowering but I'm reluctant to use the technique at this time of year. Still, the plants have few blooms & I'm getting worried.

With 20+ varieties, they are varied in growth, appearance and what I expect out of them but almost without exception: there is little to no green fruit or blossoms. The exceptions are Thessaloniki - & I'm not sure why those plants are so small this time having opted for loading up with fruit, I guess - and the mystery tomato I was going on so much about in 2011. (The seed contaminated a packet of Early Girl seed.)

The mystery tomatoes, however, are the only ones out of 60+ plants where I'm finding some kind of foliage problems. The only ripe tomato has come from 1 of those plants and there are more in the offing! Still, I'm not happy about a repeat of the problem these things had in 2011.

I sprayed Miracle Gro bloom booster on the flower garden this year. It made an obvious difference in the strength of the snapdragon stems which have broken in strong winds, some years. Not this time . . . colors are nice, also.

Synthetic fertilizers haven't been in my veggie gardens in over a dozen years. Maybe I'll stop at the garden center tomorrow & see if they have this liquid bonemeal Jay talks about.

The tomato plants look really great out there and it would be a shame if they set a crop too late. Shame? It would be a tragedy!!

Good hot July here with 9 days above 90F so far. I know that doesn't compare with what most of the country is experiencing but it is quite a turnaround from Junuary.

Up date:
Tomatoes are beginning to show in the plants. I did not know that there was any developing. I am going to get tomatoes, I just don't know how many. Still not many flowers like I normally would see. I think it is just the year. 104/60 degrees. Now that it is only about 88/98, they seem to have started to grow again. The fertilizer i used a month ago was 15/40/15 from Ace. I think I will give then another shot of it just for the heck of it. There is a lot of plants there in a small volume of dirt.
I have never had plants that big before, never! They are from 6 to 7 foot tall. The two beds are 40 inches apart and I cannot walk between them.
